3.3 VLAN Function

The switch supports port-based VLAN, 802.1Q Tag VLAN and eight VLAN groups.

3.3.1 VLAN Operation

The following figure illustrates the basic VLAN operation flow beginning from a packet received on an ingress port until it is transmitted from an egress port.

The following sections describe the VLAN processes and Advanced VLAN mode settings provided by the switch. A global setting means the setting is applied to all ports of the switch. A per port setting means each port can be configured for the setting respectively.

3.3.2 Ingress Rules

When a packet is received on an ingress port, the ingress rules are applied for packet filtering and packet tag removal. The related Ingress port settings are:

3.3.2.1 802.1Q Tag Aware Per port setting

Tag-aware-802.1Q Tag Aware mode is used. The switch examines the tag content of every received packets. For a VLAN tagged packet, the packet VLAN tag data is retrieved as packet tag information for VLAN classification and egress tagging operation. For untagged packet and priority-tagged packet, port-based mode is used.

Tag-ignore- Port-based mode is used. The switch ignores the tag content of every received packets. Ingress Port Default Tag is always used as packet tag information for VLAN classification.

3.3.2.2 Keep Tag Per port setting

Enable - The VLAN tag in the received VLAN tagged packet will be kept as it is and is not stripped in whole forwarding operation.

Disable - The VLAN tag data in the received VLAN tagged packet is stripped (removed).
